About Celestia
Celestia lets you move between celestial objects and inspect them from different positions in space. Time controls and navigation tools provide a way to explore orbital motion and scale.
It complements a ground-based planetarium by allowing free movement through a modeled universe. Additional content can expand the objects available.
